Publication number: 20140104857Abstract: The invention relates to an illuminant (23) and a socket (20) for a lamp (15). The features of the socket (20) can be implemented also independently of the features of the illuminant (23). The illuminant (23) has a preferably planar illumination surface (24). One or more semiconductor lighting elements are arranged within an illuminant housing (30). The illuminant connection device (70) required for mechanical and electrical connection to the socket (20) is provided on the rear face (66) of the illuminant (23), said rear face (66) lying opposite the illumination surface (24). The dimensions of the illuminant are preferably greater than the dimensions of the socket (10) such that the illuminant (23) fully covers the socket when looking onto the illumination surface (24), resulting in a particularly appealing look. Said socket and illuminant (23) modularly achieve large total illumination surfaces in a lamp (15) and an appealing overall appearance in a very simple manner.Type: ApplicationFiled: October 18, 2011Publication date: April 17, 2014Applicant: Koninlijke Philips Electronics N.V.Inventors: Ulrich Spintge, Karsten Diekmann, Britta Göötz, Steven Rossbach, Tom Munters, Vincent Johannes Jacobus Van Montfort

Patent number: 8471188Abstract: The present invention relates to a method and a device for controlling a physical property of light emitted from a light source. In particular, the invention can be applied to a lighting system for atmosphere creation. The measurements needed for feedback control are made at a portable user device comprising a planar photodetector. More or less all industrially available photodetectors are of the planar type, but planarity is in fact a necessary feature to achieve faithful relative measurements. Since the user device is portable, variations in the orientation of the photodetector can introduce large and unpredictable measurement errors, making effective control of the light source impossible. According to one embodiment of the invention, the orientation-dependent errors are eliminated by measuring the actual orientation of the photodetector and processing the detection signal appropriately.Type: GrantFiled: January 19, 2009Date of Patent: June 25, 2013Assignee: Koninlijke Philips Electronics N.V.Inventors: Tim Corneel Wilhelmus Schenk, Paulus Henricus Antonius Damink, Lorenzo Feri

Patent number: 8240854Abstract: An autostereoscopic display device includes a reflection layer for reflecting at least a portion of incident light, a polarization conversion layer arranged over the reflection layer, and an array of lenticular elements arranged over at least a portion of the polarization conversion layer and including a birefringent material. Light having a first state of polarization is configured to pass through the lenticular element array without substantial lenticular element focusing, where the polarization state is transformed by the polarization conversion layer such that the reflected light has a second state of polarization. Light having the second polarization state passes through the lenticular element array with the lenticular element focusing to provide multiple views to different viewing locations.Type: GrantFiled: December 12, 2007Date of Patent: August 14, 2012Assignee: Koninlijke Philips Electronics N.V.Inventors: Marcellinus Petrus Carolus Michael Krijn, Patrick Peter Elizabeth Meuwissen, Hans Zuidema, Willem Lubertus Ijzerman, Siebe Tjerk De Zwart, Oscar Hendrikus Willemsen

Patent number: 8239962Abstract: This invention relates to a method of processing rights relating to content, that can be communicated between devices. Typically, a Digital Rights Management (DRM) system imposes limitations of use and distribution, imposed by the service provider, content provider or distributor. The method of the invention renders it possible for a user who has received DRM rights to restrict the right further. The invention is more particularly related to the receipt of DRM rights to Authorized Domain Digital Rights Management (AD-DRM) systems and the introduction of user attributed rights in the form of further restrictions introduced to the received DRM rights. The invention further relates to a Rights Program Template (RPT) facilitating the introduction of such further restrictions in a user friendly way. Finally, the invention relates to a system supporting the method of the invention.Type: GrantFiled: May 10, 2005Date of Patent: August 7, 2012Assignee: Koninlijke Philips Electronics N.V.Inventors: Franciscus Lucas Antonius Johannes Kampeman, Milan Petkovic, Robert Paul Koster, Koen Hendrik Johan Vrielink

Patent number: 7521876Abstract: An electronic ballast includes open circuit voltage regulation comprises an filament current sensing circuit 224 operably connected to an output of the electronic ballast and generating a sensed output voltage signal, and a regulating pulse width modulator U3 receiving the sensed output voltage signal and operably connected to control voltage at the output of the electronic ballast, the regulating pulse width modulator U3 having an output voltage threshold limit. The regulating pulse width modulator U3 limits the voltage at the output of the electronic ballast when the sensed output voltage signal exceeds the output voltage threshold limit. The regulating pulse width modulator U3 can limit the output voltage by limiting the pulse width to the high voltage driver and the resonant half bridge. The filament current sensing circuit 224 can sense the output voltage indirectly, such as by sensing tank current, or can sense the output voltage directly.Type: GrantFiled: December 9, 2004Date of Patent: April 21, 2009Assignee: Koninlijke Philips Electronics, N.V.Inventors: William L.

Patent number: 7359524Abstract: System including a CIC hearing aid that is constructed from a first universal part containing microphone, amplifier and loudspeaker and a second part that is adapted to the auditory canal of the patient. The hearing aid is of a digitally programmable design. The programming is carried out by way of a cable. Since a connection to the first part is not easy to make on account of lack of space, it is proposed to use an auxiliary part that replaces the first part and is used for establishing the desired amplifier characteristics. The desired amplifier characteristics obtained in this way are transmitted to the first part to be used by the patient by contacts that are accessible when the aid is removed from the ear.Type: GrantFiled: December 9, 2002Date of Patent: April 15, 2008Assignee: Koninlijke Philips Electronics N.V.Inventor: Lourens George Bordewijk
